Application filed February is, 1915. serial nmasac.

To all whom, it may concern:

Be it known that 1, CHARLES J. LIN DIioLM,

a citizen of Sweden, residing at Milwaukee; Milwaukee and State of inthe county of lihsconsm, have lnvented certain new and usefulImprovements in Animal-Releasing Devices, of which the cation.

This invention relates to improvements in animal releasing devices andits object is to following is a specifiprovide a device whereby a numberof ani-' mals confined in a series of stalls may be simultaneouslyreleased in time of necessity, as in case of fire and the like.

\Vith the foregoing and other objects in view the invention consists inthe combination and arrangement of parts to be hereinafter fullydescribed in the following specification, pointed out in the claims andillustrated in the accompanying drawings which form a part of saidspecification and in which Figure 1 is a front view of my improveddevice as applied to a series of stalls in a stable. Fig. 2 is a planview of the same. Fig. 3 is a vertical section taken on the line 55 ofFig. 1; and Fig. 4c is a detailed front elevation of the inventionshowing the retaining device in released position.

Like reference characters indicate corresponding parts throughout theseveral views.

The reference numeral 1 designates the outside wall of a stable or likebuilding which in its interior is divided into a plurality of stalls bypartitions 2 in each of which the ordinary feed trough 3 is arranged. Tothe several feed troughs I secure a rotary shaft 4 by means of these"-eral brackets 5, said shaft 4 being formed with a plurality of notches 5and upon each notched portion of the shaft a bracket 6 is" secured, saidbracket 6 being apertured as at 7 and through said aperture a pin 8 isnormally projected which terminally engages the notched portion of theshaft 4. The pin 8 is carried by a flat spring 9 which is secured bybolt 10 to the bracket. The bracket 6, further, is formed in its freeend with an opening 11 through which a curved bolt 12 normally projectsthat extends into a housing 13 secured to the under side of the feedtrough. About said curved bolt a spring 14 is disposed that tends torotate said bolt. The bolt carries the ordinary hitching ring 15.Referring again to the I at an angle with the operator raises rotaryshaft 4, one end of the same extends through one end of the stable andis bent balance of the shaftand carries a weight 16 which is normallyretained in set position, shown in full lines in Fig. 41, by the springlever 17 To "release one animal from the stall the operator raises thepin 8, out of engagement with shaft A and then manually raises thebracket 6 out of engagement with the curved bolt 12 when the ring 15will be removed from the bolt by rotation of the same. To release all ofthe animals simultaneouslythe the lever 17 out of engagement with thecurved end of the shaft A when the weight 16 will gravitate into theposition shown in dotted lines in Fig. 1 and so move the shaft and allof the brackets 6 out of engagement with the curved bolts 12 permittinganimals in the stalls to escape and take the rings 15 with them.

That is claimed is:

1. A releasing device of the type described, including a longitudinalmember, means for supporting the same, a bracket movably applied to ber,a spring resting upon said bracket and having one end secured to saidbracket and provided at its opposite end with a detentlike pin arrangedto extend through said bracket and engage said longitudinal mem-' ber, ahalter or strap attaching member, and a resiliently exerted boltcontrolled by said spring-pin retained bracket, said halter orstrap-attaching member being connected to said bolt.

2. A releasing device of the type de scribed, including .a longitudinalmember said longitudinal memhaving a notch, means for supporting saidlongitudinal member, a bracket movable upon, and having saidlongitudinal member extending therethrough, aspring having one endsecured to said bracket, the opposite end of said spring being equippedwith a detentlike pin extending through said bracket and engaging anotch in said longitudinal memher, a bolt equipped with a halter orstrapattaching member, said bracket having an opening receiving one endof said bolt, and a resilient member applied to exert pressure upon saidbolt and provide for the removal of said strap-attaching member from thelatter as said bolt is disengaged from said bracket.

3. A releasing device of the type deseribed, including a rotarylongitudinal rod member, means for supporting the same, a bracketapplied to turn With said rotary longitudinal rod member, means for theretention of said rotary longitudinal rod member in set position, a boltheld in engagement With said bracket and equipped With a strap orhalter-attaching member, and a spring" applied to exert pressure upon,and cause said bolt to become disengaged from said bracket as the latterreceives movement from the turning or actuating of said rotarylongitudinal member.

In testimony that I claim the foregoing as my own I have hereto ailixedmy Signa- 15 ture in the presence Of'tWO subscribing Witnesses.
